(Prime Numbers) An integer is said to be prime if it's divisible by only 1 and itself. For ex_
ample, 2. 3, 5 and 7 are prime, but 4, 6, 8 and 9 are not.
a) Wright a function that determines whether a number is prime.
b) Use this function in a
c)Initially, you might think that is the upper limit for which you must test to sec whether a number is prime. but you need only go as high as the square root of n. Why? Rewrite the program. and run it both ways. Estimate the performance improvement.

- (Statics) A beam’s second moment of inertia, also known as its area moment of inertia, is used to determine its resistance to bending and deflection. For a rectangular beam (see Figure 6.6), the second moment of inertia is given by this formula: Ibh3/12 I is the second moment of inertia (m4). b is the base (m). h is the height (m). a. Using this formula, write a function called beamMoment() that accepts two double- precision numbers as parameters (one for the base and one for the height), calculates the corresponding second moment of inertia, and displays the result. b. Include the function written in Exercise 4a in a working program. Make sure your function is called from main(). Test the function by passing various data to it.arrow_forwardPlease the output of program.arrow_forwardPlease write out the code for this function using R.arrow_forward

Then -Define the variables complic, comorb, depressi, diabetes as factors. For all these factors, a zero means “no” and a 1 means “yes”. Assign these value labels through the function factor() and check the change using str()arrow_forwardState whether the following are true or false. If the answer is false, explain why.b) The break statement is required in the default case of a switch selection statement.arrow_forward
